This invention discloses a vision-based computer keyboard quality inspection method and system, comprising: acquiring multi-source visual inspection data of the computer keyboard to be inspected; performing image preprocessing on the multi-source visual inspection data to obtain a preprocessed keyboard image; dividing the preprocessed keyboard image into regions to obtain a detection sub-region corresponding to each key; extracting features from each detection sub-region to obtain a structural line map; inspecting the keycap surface to obtain a fused edge probability map; and determining the keyboard's structural state and appearance state based on the structural line map and the fused edge probability map. This invention enables multi-dimensional inspection of the keyboard, reduces detection and recognition errors and false positive / false negative rates, and improves the accuracy of quality inspection.

This utility model relates to the field of computer keyboard technology and discloses an anti-ghosting computer keyboard membrane switch, including a membrane body. An upper wire is disposed inside the membrane body, and a middle partition layer is disposed on the lower surface of the upper wire. The outer wall of the middle partition layer is disposed inside the membrane body, and a circular hole is formed inside the middle partition layer. A lower wire is disposed on the lower surface of the middle partition layer, and the outer wall of the lower wire is disposed inside the membrane body. A conductive line is disposed inside the lower wire, and solder pads are fixedly connected to both outer walls of the conductive line. In this utility model, through the cooperation of the upper wire, middle partition layer, circular hole, lower wire, conductive line, solder pads, UV bridge, and surface mount, effective insulation and isolation are achieved, enhancing signal stability and anti-interference, reducing the probability of accidental touches, and simultaneously realizing a precise and reliable conduction triggering function, thereby effectively preventing ghosting.

The utility model discloses a detachable keyboard's notebook computer relates to notebook computer technical field, include: the computer that is internally equipped with keyboard cavity, keyboard mechanism, be located in the keyboard cavity. This detachable keyboard's notebook computer, through the use of keyboard mechanism, can synchronous dismount keycap, and, the magnetic force ring board of embedding keyboard frame in with every keycap bottom's metal ring form magnetic attraction connection, make at the time of lifting keyboard frame, all keycap can be synchronized, neatly and together take out, greatly simplify the dismounting process, avoided the risk of losing the scattered parts, realized the integration management and maintenance of keyboard module, this detachable keyboard's notebook computer, through the use of positioning mechanism, can by an angle adjusting motor drive, through the linkage system that the synchronous sprocket, chain and cable constitute, can accurate control the synchronous rotation of multiple positioning rods at the four corners of keyboard cavity, thereby simultaneously release or lock the keyboard frame.

The utility model discloses a computer keyboard bottom plate punching device of convenient blanking, its work table upper surface fixedly connected with connecting frame, the connecting frame is concave character shape, the connecting frame inner lower surface fixedly connected with electric jar, electric jar output fixedly connected with connecting seat, connecting seat both sides surface fixedly connected with fixed plate, the fixed plate side surface is equipped with the removal groove. Through set up clamping block, fixed pad, connecting rod, rotating disc, threaded rod, mounting shaft, moving block, fixed column and link column. Reverse rotation moving block makes it under the effect of threaded rod to mounting shaft. Connecting rod drives clamping block to rotate, makes fixed pad and connecting plate separate, removes the fixedness to the punching plate. After replacing new punching plate, clockwise rotating rotating disc, moving block is far from mounting shaft, and clamping block is close to connecting plate, and fixed pad is in close contact with connecting plate, and the installation of new punching plate is completed. This improves the flexibility of device.

This invention provides a fiberglass composite keyboard cover for laptops and its preparation method, relating to the field of laptop shell technology. The keyboard cover includes a fiberglass composite substrate layer and multiple functional coatings sequentially stacked thereon: a black ink layer, a white ink layer, a decorative ink layer, a UV textured hardening layer, and an AF anti-fingerprint layer. A screen printing release layer is also provided on the lower surface of the substrate layer. The fiberglass composite layer is composed of glass fiber cloth and modified epoxy resin, and has excellent wave transmission and mechanical properties. The preparation method mainly includes sequentially screen printing and curing each functional coating on a flat substrate, followed by CNC rough machining, hot pressing, CNC fine machining, and AF coating. This invention solves the problems of signal shielding by metal materials and the cheap feel of plastic materials, achieving a comprehensive effect of no signal interference, high-end and customizable appearance, and good durability.
